What was I thinking

So today when i got home from work I went onto the deck and looked over the edge. I was so friggen upset with what I saw. You see yesterday I gave my son 20 bucks to take 4 bags of trash to the dump. That would have cost 8 bucks which left him 12 bucks for himself for gas or whatever. There was another bag of plastics that i have been recycling and then some medal stuff. So today when I look over the deck edge what do i see? A bag of garbage thrown into the woods behind my house. Not even out of site. Just right down the hill. I was so upset and pissed. He said he was the only one. But today when i went to go mow the lawn (Yeah I know he should have been the one mowing the lawn and I did ask him to, but his life is more important) anyway, low and behold is yet another bag of garbage. I told him get in there and get the bags. he walked down into the woods, and came back with nothing. gave me some line of crap about how he had sandals on and if I wanted to pay his medical bills when he gets hurt. I'M TIRED OF THIS!!!! EVERYONE is telling me to kick him out, but do I listen? no I just keep taking the abuse. I wonder how many more times he will still that knife in my back before I've had enough? It's getting close. I DO NOT DESERVE THIS!~
